Shannon took a taxi from her office to her home. Her taxi fare was based on the charges shown. The taxi stopped once at a traffic light for 3 minutes and travelled a total distance of 8.1 km to reach Shannon's home. How much was her taxi fare?

Taxi Fare
First km	$2.50
Every additional 400 m or less	$0.29
Every 45 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $2.50

Remaining distance to pay for
= 8.1 - 1
= 7.1 km

1 km = 1000 m
7.1 km = 7.1 x 1000 = 7100 m

Sets of additional 400 m
= 7100 ÷ 400
= 17 r 300

Sets of additional 400 m or less
= 17 + 1
= 18

Amount to pay for remaining 7.1 km
= 18 x 0.29
= $5.22

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 45 seconds of waiting
= 180 ÷ 45
= 4 r 0

Amount to pay for sets of 45 seconds of waiting or less
= 4 x 0.40
= $1.60

Shannon's taxi fare
= 2.50 + 5.22 + 1.60
= $9.32

Answer(s): $9.32
